Expanded mesh

Expanded / perforated mesh is a kind of metal mesh produced by cutting and pulling a simple solid steel. Cutting is performed along the entire width of the sheet iron. Depending on the tools and the material thickness, the final product can be either a sheet or a coil.
Expanded mesh is made of black steel, aluminum, stainless steel, galvanized steel, bronze or brass.
Depending on the shape of the tool, many different types of aperture can be obtained, typically diamond, square, circle and hexagon in shape. The mesh is made of sheet iron with a thickness of 0.5 to 1.5 mm.
In recent years, perforated and expanded meshes are becoming increasingly popular in architecture and interior design where aesthetic qualities are valued higher than in manufacturing of industrial products. Consequently, there is a wide variety of aperture shapes, a few of which are shown below.
